I have no actual data about the musical signals present on the discs themselves (be they made of any kind of plastic with grooves or pits), I just mentioned the technological limitations of them. ( see also https://wiki.hydrogenaud.io/index.php?title=Myths_(Vinyl)#My... )
However, as far as I know the loudness wars is coming to an end finally: https://en.wikipedia.org/wiki/Loudness_war#2010s "Analysis suggests that the loudness trend may have peaked around 2005 and subsequently reduced, with a pronounced increase in overall and minimum album DR (crest factor) for albums since 2005."
